ENDOVASCULAR MANAGEMENT OF BLEEDING ILIAC ARTERY PSEUDOANEURYSMS COMPLICATING RADIATION-THERAPY FOR PELVIC MALIGNANCIES

OBJECTIVE. We evaluated arteriographic findings and endovascular treat ments of eight patients who had bleeding iliac artery pseudoaneurysms and who had undergone radiation therapy (3000-6500 rad [30-65 Gy]) and surgery for pelvic malignancies. CONCLUSION. Angiography revealed con trast media extravasation in 75% of patients who had bleeding iliac ar tery pseudoaneurysms and failed to show the source of bleeding in 25%. The patients who had positive findings at angiography were all succes sfully treated percutaneously, although two patients required addition al bypass surgery. Among embolic materials, coils and balloons were sa fe and efficient, whereas cyanoacrylate was unsafe and led to complica tions in two of three patients. A covered stent, which was not availab le for most of our patients, was used in one patient and may be an eff ective means of treating pseudoaneurysms.
